This is the module only - does not include hose or boot.The Apeks submersible pressure (contents) gauge, with an internal Bourdon pressure measuring mechanism, gives you clear information on the gas contents of your cylinder. The gauge indicates the cylinder bottle pressure and the dial range is from zero to 360bar. The dial face is designed with clarity in mind by being uncluttered, with large black figures on a luminous background giving a long phosphorescent effect. This makes viewing as easy as possible, even in poor visibility conditions.

• The gauge case is made from nickel plated brass

• The dial window is made of highly shock resistant material (anti-splinter polycarbonate)

• There is an over-pressure capsule fitted in the back of the module to prevent the screen from exploding in the unlikely event of the internal mechanism failing.
